I have experienced the controller locking me out from the mobile app while no stations are in use, only to start working again a short time later without resetting controller. I can’t recall if this was only while in ethernet mode, in wifi or both. I’ve been troubleshooting this since February between everything else going on, so I’ve lost track of some details. What got me to suggesting the ethernet connection was the consistency at which I would have a stuck valve while using ethernet. I haven’t been able to see this problem in wifi so until then I can’t rule out the ethernet.
What would a “hardware based TCP/IP stack ethernet module” entail? I’m wondering if that is something I could do? Though I don’t have the skill to code…I would gladly buy a module if that solves the problem for me.
